Beyond Linux From Scratch - Version 6.2.0

Chapter 1. Welcome to BLFS

Getting the Source Packages

Within the BLFS instructions, each package has two references for
finding the source files for the package—an HTTP link and an
FTP link (some packages may only list one of these links). Every
effort has been made to ensure that these links are accurate.
However, the World Wide Web is in continuous flux. Packages are
sometimes moved or updated and the exact URL specified is not always
available.

To overcome this problem, the BLFS Team, with the assistance of
Server
Beach, has made an HTTP/FTP site available at anduin.linuxfromscratch.org. This site has
all the sources of the exact versions of the packages used in BLFS.
If you can't find the BLFS package you need, get it there.

We would like to ask a favor, however. Although this is a public
resource for you to use, we do not want to abuse it. We have already
had one unthinking individual download over 3 GB of data, including
multiple copies of the same files that are placed at different
locations (via symlinks) to make finding the right package easier.
This person clearly did not know what files he needed and downloaded
everything. The best place to download files is the site or sites set
up by the source code developer. Please try there first.
